The present invention relates to 4shock in.-

- sulators.

More particularly the present inventlonre-v lates to means forinsulating or absorbing the shocks which occur between lthe trans-'mission mechanism and the frame of an automobile. The supporting meansformount-A .v ing the transm1ss1on box of an automobile upon the trame.thereof will wear. due to",

-is substantially circular incross section. Said projecting portion 6 issupported' from the cross bar 4 by means of the bracket 7 v'andthe ringmember 8. VSaid ring member. 8 will be composed of rubber or other cush-'ioning material and will absorb shocks between the cross vbar 4 and thetransmission `casing 2 and prevent squeaks, which are A.frequently setup by. reason of vibration be- 10 the vibration encountered in serviceand wilfztween the transmission caslng and its supbecomefnoisy. 4Evenbefore wear has 'occurred, the metal-to-metal contact will producevsquea-ks due to twists in the frame and corresponding relative motionbetween the surfaces of the supporting andsupported parts. v

An object of the present invention is to provide a construction 'inwhich the noises above referred to are avoided.

A further-object is to provide a support adapted tohold the transmissioncasing of an automobile, which support is .simple in construction andwhich will etfectuall'y ab- 1 sorb the shocks encountered in service.

scription proceeds.v Referring'to the drawings- Figure l is a more orless diagrammaticw plan view of an automobile frame having 4atransmission `box mountedthereon;

Figure 2 isa fragmentary View onl line 2 2'- of Figure l, on -anenlarged' scale, of part of the trame of an automobile, the transmissioncasingA and the Supporting means'embodying the present invention; andFigure 3v is a view taken at right angles to the view-shown in Figure 2.

The numerals ll' indicatethe side frame members of the. chassis of anautomobile. Thegnumeral'2 indicates atransmission casing, whichissupportedV by the two cross bars 3 and 4, which cross bars aresupported by the side frame -members 1'-1.

A bile is commonly supported from three points, and the presentinvention contemplates such a suspension, one extremity of thetransmission Casing being united to the cross bar 3 at the two points 55. For

mlssion caslng a special construction is provided, which will nowbe'described. 'Referring particularly to Figures 2 and 3, it will benotedthat the transmission casing Further objects will appear as the de;

The transmission casingof an automosupporting the other extremity of thetrans' 2 has an axially projecting portion 6, whichporting member.

The -bracket'l' comprises a radially split ring uportion 9 and theoutstanding lugs- 10-10, which lugs 10--10 may be bolted to the crossbar 4. The two extremities of the split ring 9 are provided with thebosses 11--1'1, which'bosses .provideseats through which pressure may beexerted upon the ring 8 bymeans of the bolt 12. The split ring 9 isAprovided with the inwardly extending flanges 13-13, which flanges areadapted touengage thetwo sides of the ring member 8 for holding saidmember 8 in proper position within said split ring 9 and for the furtherpurpose of limiting the region of flow 'of the ring member 8 when saidring member vis put into astate of compression.

In service-the ring 8 will flow under shock, the extent of How beingrestrictedJ by means of the flanges 13e-13.

By reason of the present invention a sim- .'ple structure is providedwhich effectually reduces noise and wear due to vibration. lt willv beclear that either vextremity of the transmission casing may be providedwith the cushioning means above described. It

' will also be .clear that many modiications over the-describedembodiment of the present invention will occur to those skilled in theart. It is intended to cover all such modifications that fall within thescope of the appended claims.

What is claimed is:

1. In combination, the frame of an automobile, a pair of cross barscarried. by said frame, a casing, means for connecting one extremity ofsaid casing toone of said bars, and means for supporting the otherextremity -of said casing to the 'other of said bars,

said means including a cushioning ring,an m5 adjustable unitary splitring encircling` said cushioning ring, means forsupportingsaid splitring from said other bar, and means for adjusting the pressure ofsaid'split ring upon said cushioning ring, said split ring beingprovided with flanges at iheextreini-V cushioning ring, said split-ringbeing 4fas- 10 l ties of said .cushioning ring for limiting the tened tosaid automobile, said split ring be'- ilow of said cushioning ring.
